Salkind (Ed.), Encyclopedia of research design (pp. Whether cultivated habitats can support threatened but flexible primates such as chimpanzees in the long term hinges on local people’s willingness to share their landscape and resources with them.Ībdi, H. Nonnutritional factors, e.g., similarity to wild foods, probably also influence crop selection. We found little evidence that crops ignored by the chimpanzees were less nutritious than those that they did eat. Our data support the assumption that eating cultivated foods confers energetic advantages for primates, although crops in our sample were low in protein and lipids compared to some wild foods. Cultivated fruits were relatively nutritious throughout the ripening process. Compared to wild food equivalents, crops eaten by the chimpanzees contained higher levels of digestible carbohydrates (mainly sugars) coupled with lower amounts of insoluble fiber and antifeedants. Our analysis of their wild plant diet (fruit, leaves, and pith) corresponds with previous chemical analyses of primate plant foods. In addition, we analyzed 13 crops not eaten at Bulindi but that are consumed by chimpanzees elsewhere to assess whether nutritional aspects explain why chimpanzees in Bulindi ignored them.
We measured the macronutrient and antifeedant content of 44 wild and 21 crop foods eaten by chimpanzees ( Pan troglodytes schweinfurthii) in a mosaic habitat at Bulindi, Uganda, to evaluate the common assertion that crops offer high nutritional returns compared to wild forage for primates. Many wild primates include cultivated foods (crops) in their diets, calling for an improved understanding of the costs and benefits of crop feeding. Primate habitats are being transformed by human activities such as agriculture.
